About the Role

We’re seeking a Senior Data Scientist to help us evaluate and improve the quality and performance of our AI systems. You’ll develop rigorous approaches to measuring system behavior, run experiments, investigate issues, and turn complex data into actionable decisions.

This is a hands-on role at the intersection of data science, engineering, and applied AI. You’ll work directly with production data and systems and partner closely with Engineering, Product, and Analytics.

Responsibilites

• AI Evaluation: Develop quantitative methods and tooling to evaluate AI system quality and performance.
• Experimentation: Design and run experiments to compare approaches, understand tradeoffs, and measure the impact of changes.
• Quality Monitoring: Build repeatable processes to identify regressions, anomalies, and changes in system performance.
• Data Analysis: Extract, transform, and analyze production data to support technical and product investigations.
• Technical Investigation: Diagnose complex issues involving data, models, and production systems, identifying root causes and potential solutions.
• Measurement & Instrumentation: Partner with Engineering to improve how system quality, reliability, and performance are measured.
• Internal Tooling: Build tools and dashboards that make system performance easier to understand and monitor.
• Communication: Clearly communicate findings, tradeoffs, and recommendations to technical and non-technical stakeholders.

Qualifications

• Master's degree in computer science, data science, machine learning, or a related field with substantial hands-on experience; or 2–4 years of relevant professional experience.
• Strong Python and SQL skills and experience working directly with production data.
• Comfortable navigating production code and data systems you did not build.
• Strong foundation in applied statistics, experimentation, and quantitative analysis.
• Practical experience working with and evaluating modern AI/ML systems.
• Experience diagnosing complex issues involving data, models, or production systems.
• Ability to turn ambiguous questions into structured investigations and clearly communicate the results.

Bonus Qualifications

• Experience building AI/ML evaluation frameworks, benchmarks, or monitoring systems.
• Experience with information retrieval, search, or large-scale information systems.
• Familiarity with modern cloud data platforms and production data infrastructure.
• Experience building internal analytics or observability tooling.

Salary Range ($160K- $200K) plus health insurance and equity.
